Dear Colleagues,

Lightweight materials and carbon fiber-reinforced composites have recently found considerable use in the automotive and aerospace sectors, allowing to address issues related to environmental regulations, fuel price, and industrial demand. The industrial uptake of carbon fibers in other industries is still severely limited by the cost associated with the petroleum-derived polyacrylonitrile (PAN) precursor and the high energy requirements for the conversion of precursor fibers into high-quality (stiff and strong) carbon fibers. In order to reduce the production costs, there is currently a great demand for new approaches and methods to manufacture carbon fibers with high mechanical properties, while consuming less energy.

In the recent decades, there has been a renewed research interest in the use of bio-based or renewable precursors such as rayon, bio-acrylonitrile, and lignin, and of low-cost synthetic precursors such as polyethylene. On the other hand, significant research efforts have also been addressed towards reducing the energy costs or production costs in a number of ways, including the optimization of fiber processing conditions, the tailoring of PAN comonomer compositions, and the synthesis of high-molecular-weight PAN by reversible addition–fragmentation chain-transfer (RAFT) polymerization.

This Special Issue of Fibers intends to cover recent advances in renewable or sustainable precursors for carbon fibers and solicits contributions from researchers active in reducing the energy requirements in the stabilization and carbonization stages and in optimizing alternative, cost-effective precursors and the use of nanoadditives in carbon fiber manufacturing.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Fibers is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
